To all when?, 'lit may concern..

[Be it' known that I, AUGUSTE Aam-ina UAILLE, a citizen of the United States of Amen` ica, residing at Detroit, in theI county ot' Wayne and State oi' Michigan, have invented certain new and useful Improvements in Coin-Controlled Lifting-Machines, of which the following' is a specification,reference being had therein to the accompanying' drawings.

This invention relates to improvements in coin-controlled lifting-machines; and its object is to provide a simple, cheap, and eflicientconstruction which is not liable to get out ol" order or be broken; and to this end the invention consists in the novel construction, arrangement, and combination ol parts, all hereinafter more fully described, and shown in the accompanying' drawings, in which Figures 1 and E2 conjointly form a transverse vertical section of the vertical casing oi' a de vice embodying the invention, showing' the operating' mechanism in elevation looking t'rom the rear of the machine. Fig'. 3 is a lon gitudinal vertical section ot' the same with the middle portion of the casing broken away for the purpose of shortening the ligure. Fig'. 4 is a detail showing' the locking mechanism in elevation; Fig. 5, an edg'e view of the same; Fig. 6, a section on the line .fr .fr of Fig'. 4, and Fig'. T an elevation showing' the parts in a dit-t lerent position from that shown in Fig. 4.

A is the base, from the rear end of which rises the vertical casing' B, and on the upper end ol this casing' is secured the head or indicater-casing (l. From the, Ylforward end ol the base rises a hollow post A, within which is the longitudinally-movable draft-rod l, screwtln'eaded at its upper end lor the engagement ot' an adjustable handle 2 and at its lower end provided with a washer 3, held thereon by a transverse pin, said washer engaging the lower edge ot' the forked end olE a lever 4, located in the base. The opposite end ot' said lever4 engages an opening' in a hook 5, attached to the lower end of a heavy coiled spring 6, adjustably supported at its upper end by a hook 7, the screw-threaded shank o'l which passes through an opening in a bracket secured to the forward side of the casing B and provided with a nut engaging the upper side ot' the bracket. A.. knife-edge pivot-bearing 8 on the base engages the upper edge ot' the lever 4 intermediate its ends, and a screw -threaded sleeve 9 on the rod 1 engages the upper end of the post A to limit the downward movement ot said rod, so that the lever 4 is held at all times by the spring@ against its bearing 8 to rock thereon.

Secured within the indicatorfcasing C is a dial 10, provided with suitable g'rrufluations, and projecting in the axis of thisdia-l is a short shalt Al 1, to the end ol which an indicator hand or pointer 1 2 is secured to point ol'l' on the dial the number olI pounds lilted by the 'operator against the action ol the spring (l. To turn this shaft and its pointer, a sprocketwheel 13 is secured to the shaft, and this sproclmt-wheel is engaged by a sprocket-chain 14, attached at one end to a coiled spring' 15, secured at the opposite end to the casing, and the opposite end ol' the chain is attached to a wire 1G, which is attached to the verticallymovable bar 17 ol the coin-controlled locking mechanism 1S. The lower end olf the bar 1T is connectedby a wire 19 to a laterally-extending arm Q0 on the end ot' the lever 4, so that as the operator pulls upward on the handle the downward movement of said end will pull on the chain against the action ol'I the spring' 15 and turn the indicating-bami. To prevent the hand trom being' turned backward by said spring as soon as thehandle is released by the opin'ator, the locking' mechanism 18 is provided, and operating' in conjunction with said mechanism to lock the lever 4 and its handle. against being' operated until a coin is inserted lio release the hacking' mechanism` a hook 21 is pivotally secured to the casing above the arm QOand falls by gravity into engagement with said arm, hooking beneath the same.

The coin-controlled locking mechanism 18 consists ol a base-plate 22, secured to the wall of the casing' and provided with ears 9.3, having' openings to receive the vcrtically-movable bar 1.7 and Jforming bearil'igs therefor, within which it is guided and lreely movable. Secured to the lower end ol said bar 17 is a sheet-metal flange 24, provided with an opening through which the rod or wire 19 extends, said wire being bent at right angles near its IOO ' bar 17. On the upper edge of the lever 28 is the parts the machine may be again operated and will indicate on the dial the number ot' pounds lifted, as when the leverl 4 is rocked l upper end to engage the flange when the wire l is -inoved bythe movement of the lever 4 and move said bar longitudinally downward. As l shown in Fig. 4, the bar is locked in the position to which it is moved by the rod 19 by a cam -lever 25, provided with a rounded shoulder 26 to engage the edge ot' the bar and pivoted at 27 to one end of a fiat lever 28, which lever is in turn pivoted intermediate its ends at 29 to the base-plate 22, the opposite end of said lever projecting beneath the a post 30, and on the lower edge of' the camlever is a similar post, to which posts the ends ot' a coiled spring 31 are attached to normally hold the upper edge of the cam-lever against the post 30, which thus t'orms a stop therefor, and on an upwardly-projecting portion of the base-plate is a post, to which one end ofl a coiled spring 32 is attached, its opposite end being attached to the lever 28 between its pivot 29 and its end to which the cam-lever is pivoted to turn said lever 28 on its pivot. On the end of the lever 28 adjacent to the pivot 27 is a projecting shoulder 33, adapted to be engaged bya weighted latch 34, pivoted intermediate its ends at 35 and having an upwardly-projecting hook 36, an arm forming a weight 37 at one side'ofl the pivot, and a laterally-projecting arm 38 at the opposite sideA of the pivot to project into the coin-chute 39. so that a coin inserted in the chute will f'all upon the end of said arm 38 and rock the latch on its pivot to release the lever 28, which will then be turned on its pivot by the spring 32 until a projection on its lower edge engages a stop 40 on the base-plate.

As soon as the latch 34 is operated by a coin to release the lever 28 the cam-lever 25 will be turned,with the lever 28, upon its pivot 29 away from the bar 17 and will be engaged by thepost 30 andheld with its cam-shoulder 26 out of engagement with said bar. thus releasing the same and allowing the coiled spring l5, through the medium of the chain 14 and rod 16, to lift the said bar to the position shown in Figs. 1 and 2 and in dotted lines in Fig. 4, this movement of the chain operating to return the indicating-hand back to zero from the position to which it had been turned by a previous lift or operation ot' the machine.

On the bar 17 is formed a lug 41, projecting toward the base-plate, and inthe edge of' the bar adjacent to said lug is formed a slight depression 42, so that when said bar is released and raised said lug will engage the ends of' the levers 25 and 28, projecting beneath said bar, and turn the same upon the pivot 29, thus allowing the latch 34 to rengage the shoulder 33, said depression allowing the camlever to be turned,with the lever 28, into the position shown in Fig. 1. In this position of on its pivot-bearing the rod 19 will be moved downward, thus moving the bar 17, as said bar is not locked against downward movement by the cani-lever, which upon such movement will be turned on its pivot 27 against the action of the spring 31. The bar 17 will, however, be prevented by said cam-lever from being raised by the spring 15 upon the release of the handles by the operator, as its rounded end or shoulder 26 is held in contact with the edge ot' the bar by the spring' 31 at a point slightly below a horizontal .line drawn through its pivot 27,and therefore said cam-lever forms a wedge between its pivot and the bar to hold the -bar against upward movement in its bearings.

The parts as shown in full lines inv Fig` 4 are in the position in which they are left af'ter each operation, and to prevent the machine from being again operated without first putting in a coin the gravity-hook 21, before described, is provided, which hook is operated to release the arm 2O and allow the machine to be operated by providing said hook with a projecting arm or lug 43, to which onev end of' a wire or rod 44 is attached, the opposite end of' said wire being extended through an opening in the flange 24 on the lower end of' the bar 17 and bent at right angles to engage the upper side of said flange. This rod 44 is of such a length that when the bar 17 is in the position shown in Fig. 1 or after having been released by the dropping of a coin and raised by the spring 15 the hook 21 will be raised out ofl contact with the arm 20, and thus the indicator is turned to zero and the lever 4 released by the dropping ot' the coin. Said hook 21 being suspended from the flange 24 when the bar 17 is in its raised position, as soon as said bar is lowered the hook will fall by gravity, and as the rod 19 by the engagement of its bent end with said flange is the medium for moving' said bar it is necessary that said rod be made of' such a length that the arm 2O may be moved downwardv a short distance past the shoulder of the hook before the bent end ofl said rod will engage the flange and move the bar 17 to allow the hook to fall. A stop 45 on the hook limits its movement, so that when the operator lets up on the handle the arm 2O will engage and pass the hook, which willf'all by gravity into engagement with the arm and lock the same until the hook is again raised out ot' contact therewith by the coin-actuated mechanism.

Secured to the casing below the locking mechanism is a plate 46, upon which is supported a bell 47, and on the plate is pivotally mounted an arm 48, carrying the bell-hammer, said arm being turned against the action of a spring to actuate the hammer by a laterallyextending pivoted dog 49, adapted to be engaged by the flange 24 on the downward movement ot' the bar 17 said dog being so posi- .tioned relative to the bar that the bell will be IOO sounded when the indicator has been turned to a certain predetermined point or when a certain amount has been lifted by the operator.

The parts being constructed and arranged as described, they are intended to operate as follows: lhen a coin is inserted, the bar '17 is released and is lifted by the spring 15, returning the indicator-hand to zero and through the medium of the rod 44 lifting the hook 2l out of the path of the arm 20, all as hereinbefore described, and therefore when the operator lifts on the handle, thus rocking the lever i on its bearing against the action of the spring 6, the arm 2O on said lever will be moved downward, carryingI with it the rod 19, the upper bent end of which rod will engage the flange 24 after said arm has passed the shoulder of the hook 21 and will pull the bar 17 downward. This downward movement of said bar turns the indicator-hand against the action of the spring l5, and said hand is held in that position by the cam-lever 25, which prevents the bar from being moved upward until another coin is dropped in, the camlcver, as previously described, having' been again set by the upward movement of the bar after having released the saine upon the insertion of the previous coin. Upon the release of the lifting-handle by the operator the end of the lever carrying the arm 2() is raised by the spring 6, and as the hook 21 was permitted to fall by its own gravity into the path of said arm when the bar 17 was pulled downward by the previous downward movement of the arm said hook will be engaged and turned by the arm as the same moves upward and will hook beneath said arm, preventing any further manipulation whatever of the device until another coin is inserted. lf it were not for the hook, any number of lifts might -be made without inserting' more than one coin, as the lever 4 would be free and the indicator would be turned each time, provided the last lift vi s greater than the one before.
